Description

Technical Field

[0001] The present invention belongs to the technical field of furniture welding, and specifically relates to a furniture production welding machine. Background Art

[0002] Furniture refers to a large category of essential utensils and facilities for humans to maintain normal life, engage in production practice, and carry out social activities. Furniture has also been continuously developed and innovated with the progress of the times. Nowadays, it has a wide variety of categories, different materials, complete varieties, and various uses, and is an important foundation for establishing a working and living space; Metal furniture is furniture mainly made of metal pipes, plates, or rods, etc., and is equipped with wood, various artificial boards, glass, stone, etc., and iron furniture completely made of metal materials, collectively referred to as metal furniture. The so-called "steel-wood furniture" should be understood as metal furniture in the professional concept. Steel-wood furniture is only one type of metal furniture. Metal furniture can well create different atmospheres required in different rooms of the family, and can also make the home style more diversified and more modern. The advantages of metal furniture are: extremely personalized style, rich color choices, diverse categories and varieties, having a folding function, quite aesthetic value, and good quality and low price.

[0003] A patent with the publication number CN210878202U discloses a new type of furniture mesh panel welding machine, including a gantry seat. A fixed plate is installed on the upper part of the gantry seat, and a fixed seat is installed on the fixed plate. A screw rod is movably connected to the fixed seat, and one end of the screw rod is connected to a driving motor. Slide seats are arranged on both sides of the screw rod. The screw rod is threadedly connected to the first welding machine. A first welding head is arranged on the first welding machine. Activity holes for movably connecting with the first welding head are arranged on the gantry seat and the fixed plate. For this new type of furniture mesh panel welding machine, through the coordinated use of the gantry seat, driving motor, first welding machine, second welding machine, and moving rollers, the two second welding machines weld the side mesh through the second welding heads, and the first welding machine moves back and forth along the X-axis through the driving motor and the screw rod to weld the middle part of the mesh panel. Welding is carried out simultaneously horizontally and vertically, improving the welding efficiency and having high stability.

[0004] In the current existing technology, after the existing furniture is produced, in order to maintain the integrity of the furniture, welding treatment needs to be carried out on the metal plates. Since most iron plates are in sheet form, when welding later, employees need to hold up the plate with one hand and weld the butt joint of two iron plates with an arc welding torch. However, manual support cannot maintain the verticality of the iron plate, and it is easy to shake during welding, resulting in the problem of welding inclination of the iron plate.

[0005] Therefore, the present invention provides a furniture production welding machine. Summary of the Invention

[0006] To make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0008] Preferably, a sunken groove is formed on the top surface of the swinging lifting plate, the bottom surface of the pushing plate is movably lapped on the inner wall surface of the sunken groove, and elastic anti-slip strips are arranged on the inner wall surface of the side limiting plate.

[0009] Preferably, the outer surface of the elastic anti-slip strip is movably lapped on the outer surface of the furniture iron plate, and an R-shaped fillet is formed on the top surface of the swinging lifting plate and located at one edge position.

[0010] Preferably, moving rollers are arranged on the top surface of the support processing table, a lapping limiting groove is formed on the top surface of the support processing table and located on the bottom surface of the swinging lifting plate, and hydraulic rods are symmetrically and fixedly installed on the outer surface of the support processing table.

[0011] Preferably, limiting rods are movably sleeved on both side surfaces of the support processing table and located at both edge positions of the hydraulic rods, and a fitting positioning plate is fixedly connected to the output end of the hydraulic rod and one end of the limiting rod.

[0012] Preferably, the fitting positioning plate is arranged at the top edge position of the moving roller, and an anti-slip soft strip is fixedly connected to the outer surface of the fitting positioning plate.

[0013] Preferably, a raised inclined groove strip is arranged on the outer surface of the fitting positioning plate and located at the bottom edge position of the anti-slip soft strip, and the outer surfaces of the anti-slip soft strip and the raised inclined groove strip are movably lapped on the outer surface of the furniture iron plate.

[0014] Preferably, a lapping plate is fixedly connected to the outer surface of the top of the support arm, and limiting grooves are formed on the inner wall surfaces on the upper and lower sides of the lapping plate.

[0015] Preferably, a first motor is fixedly installed on the inner wall surface of the lapping plate, and a threaded rod is fixedly connected to the output end of the first motor.

[0016] Preferably, a slider is threadedly sleeved on the outer surface of the threaded rod, and an arc welding head is fixedly installed on the outer surface of one end of the slider.

[0017] The beneficial effects of the present invention are as follows: 1. For a furniture production welding machine of the present invention, after the furniture iron plate is positioned, the second motor is used to rotate the limiting roller, so that the swinging lifting plate at one end of the limiting roller rotates around the support processing table as a pivot point. At this time, the falling telescopic plate is used to limit the height of the furniture iron plate, and the swinging lifting plate is perpendicular to the top surface of the support processing table. After being perpendicular, the furniture iron plate will be edge-to-edge attached to another furniture iron plate on the top surface of the support processing table, so that the two furniture iron plates can be effectively lapped together. At this time, the two furniture iron plates are perpendicularly attached to each other, which is convenient for subsequent workers to effectively weld the gaps between the two furniture iron plates; 2. For a furniture production welding machine of the present invention, the furniture iron plate is placed on the top surface of the support processing table, and the furniture iron plate is pushed to slide on the top surface of the moving roller. When the position of the furniture iron plate moves to a suitable position, the hydraulic rod is used to push the fitting positioning plate, and the furniture iron plate is lifted and tilted by the heightening inclined groove strip on the outer surface of the fitting positioning plate, so that a cavity for heat dissipation and exhaust gas emission is left between the furniture iron plate and the support processing table. The anti-slip soft strip on the outer surface of the fitting positioning plate increases the friction and anti-slip property with the surface of the furniture iron plate, so that the furniture iron plate can always be in a positioned state; 3. For a furniture production welding machine of the present invention, after the two furniture iron plates are welded, they will form an L-shaped state. At this time, the fitting positioning plate is used to loosen the surface of the furniture iron plate, and the second motor is used to rotate the swinging lifting plate in the reverse direction. Since the surface of the pushing plate has been pressing against the surface of the furniture iron plate, the firmly fixed furniture iron plate will rotate together with the rotation of the swinging lifting plate. At this time, the output end of the falling telescopic plate is retracted, and then the third motor is used to push the pushing plate, as Figure 2 shown, the furniture iron plate is moved to the top surface of the moving roller, and then the position of the furniture iron plate is squeezed and clamped by the fitting positioning plate; 4. For a furniture production welding machine according to the present invention, a new piece of furniture iron plate is re-lapped on the top surface of the swinging lifting plate, and the current operation is repeated. A new piece of furniture iron plate is lapped on the surface of the furniture iron plate after welding, as Figure 3 described. When three pieces of furniture iron plates are welded, as Figure 4 and Figure 5 shown, the current steps are repeatedly operated. Then, after four pieces of furniture iron plates are welded, the sliding force on the bottom surface of the furniture iron plate is increased by cooperating with the moving rollers, so as to lift the furniture iron plate off the top surface of the support processing table; 5. For a furniture production welding machine according to the present invention, when the furniture iron plates on the outer surfaces of the support processing table and the swinging lifting plate are vertically butted, the motor in the first motor rotates the threaded rod. Under the limitation of the limit groove, the slider moves into the furniture iron plate. At this time, the arc welding head on the outer surface of the slider welds the joint of the two furniture iron plates. By using two arc welding heads for welding at the same time, the welding time and welding path can be greatly reduced, so that the two furniture iron plates can be quickly positioned and fixed together.

Specific implementation manner

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 7 and Figure 9 shown, a furniture production welding machine according to an embodiment of the present invention includes a support processing table 11 and support arms 12 symmetrically and fixedly installed on both side surfaces of the support processing table 11, a furniture iron plate 13 movably lapped on the outer surface of the top of the support processing table 11, a motor 2 14 symmetrically and fixedly installed on both side surfaces of the support processing table 11 and located at one side edge position of the support arm 12, a limiting roller 141 fixedly connected to the output end of the motor 2 14 and movably sleeved on the outer surface of the bottom of the support processing table 11, a swinging lifting plate 142 fixedly connected to one end of the limiting roller 141, the bottom surface of the swinging lifting plate 142 movably lapped on the top surface of the support processing table 11, a motor 3 145 fixedly installed on the top surface of the swinging lifting plate 142 and located at both side edge positions, a lead screw fixedly connected to the output end of the motor 3 145, a pushing plate 146 threadedly and movably sleeved on the outer surface of the lead screw, a side limiting plate 147 fixedly connected to the top surface of the swinging lifting plate 142 and located at one side edge position of the motor 3 145, a downward telescopic plate 148 fixedly installed at one end of the side limiting plate 147, and the outer surfaces of the pushing plate 146 and the downward telescopic plate 148 movably lapped on the outer surface of the furniture iron plate 13.

[0023] Place the furniture iron plate 13 on the top surface of the swinging lifting plate 142, and limit the position of the furniture iron plate 13 through the side limiting plate 147. At this time, rotate the lead screw through the motor 3 145, so that the pushing plate 146 on the surface of the lead screw pushes the furniture iron plate 13. At this time, extend the downward telescopic plate 148 to limit the position of the furniture iron plate 13 to achieve the effect of multi-angle limitation of the furniture iron plate 13 by using the downward telescopic plate 148 and the pushing plate 146; After the furniture iron plate 13 is positioned, the second motor 14 is used to rotate the limiting roller 141, so that the swing lifting plate 142 at one end of the limiting roller 141 rotates around the support processing table 11 as the axis point. At this time, the falling telescopic plate 148 is used to limit the height of the furniture iron plate 13, and the swing lifting plate 142 is perpendicular to the top surface of the support processing table 11. After being perpendicular, the furniture iron plate 13 will be edge-to-edge with another furniture iron plate 13 on the top surface of the support processing table 11, so that the two furniture iron plates 13 can be effectively overlapped. At this time, the two furniture iron plates 13 are perpendicularly attached to each other, which is convenient for subsequent workers to effectively weld the gaps between the two furniture iron plates 13. It avoids the need for workers to support and hold the two furniture iron plates 13 with one hand when welding metal plates, preventing the furniture iron plates 13 from shaking and making it difficult to perform welding operations.

[0024] As Figures 1 to 6 and Figure 9 shown, a sunken groove 144 is formed on the top surface of the swing lifting plate 142. The bottom surface of the push plate 146 is movably lapped on the inner side wall surface of the sunken groove 144. Elastic anti-slip strips 149 are arranged on the inner side wall surface of the side limiting plate 147. The outer surface of the elastic anti-slip strips 149 is movably lapped on the outer surface of the furniture iron plate 13. An R-shaped fillet 143 is formed on the top surface of the swing lifting plate 142 and at one side edge position.

[0025] When the furniture iron plate 13 is placed on the outer top surface of the swing lifting plate 142, the side limiting plate 147 is used to limit the two side surfaces of the larger furniture iron plate 13. When facing the smaller furniture iron plate 13, the elastic anti-slip strips 149 on the inner side wall surface of the side limiting plate 147 are used to push the furniture iron plate 13, so that the furniture iron plate 13 is always located at the center position of the swing lifting plate 142, thus facilitating the effective butt welding of the two furniture iron plates 13.

[0026] As Figures 1 to 6 and Figure 8As shown, a moving roller 111 is provided on the top surface of the supporting processing table 11, and an overlapping limit groove is opened on the top surface of the supporting processing table 11 and on the bottom surface of the swing lifting plate 142, and a hydraulic rod 112 is symmetrically fixedly installed on the outer surface of the supporting processing table 11, and a limit rod 113 is movably sleeved on the two side surfaces of the supporting processing table 11 and on the two side edge positions of the hydraulic rod 112, and a fitting positioning plate 114 is fixedly connected to the output end of the hydraulic rod 112 and one end of the limit rod 113, and the position of the fitting positioning plate 114 is set at the top edge position of the moving roller 111, and an anti-skid soft strip 115 is fixedly connected to the outer surface of the fitting positioning plate 114, and a padding oblique groove strip 116 is provided on the outer surface of the fitting positioning plate 114 and at the bottom edge position of the anti-skid soft strip 115, and the outer surfaces of the anti-skid soft strip 115 and the padding oblique groove strip 116 are movably overlapped on the outer surface of the furniture iron plate 13.

[0027] Place the furniture iron plate 13 on the top surface of the supporting processing table 11, push the furniture iron plate 13 to make it slide on the top surface of the moving roller 111, and when the position of the furniture iron plate 13 moves to a suitable position, cooperate with the hydraulic rod 112 to push the fitting positioning plate 114, and use the raised inclined groove strip 116 on the outer surface of the fitting positioning plate 114 to lift and tilt the surface of the furniture iron plate 13, so that a certain cavity for heat dissipation and exhaust gas emission is left between the furniture iron plate 13 and the supporting processing table 11, and the anti-slip soft strip 115 on the outer surface of the fitting positioning plate 114 increases the friction and anti-slip property between the furniture iron plate 13 and the surface, so that the furniture iron plate 13 can always be in a positioned state.

[0028] like Figures 1 - 2 and Figures 6 to 7 As shown, a lap plate 121 is fixedly connected to the top outer surface of the support arm 12, and limiting grooves 122 are provided on the upper and lower inner wall surfaces of the lap plate 121. A motor 123 is fixedly installed on the inner wall surface of the lap plate 121, and a threaded rod is fixedly connected to the output end of the motor 123. A slider 124 is threadedly movably sleeved on the outer surface of the threaded rod, and an arc welding head 125 is fixedly installed on the outer surface of one end of the slider 124.

[0029] After the furniture iron plate 13 on the outer surface of the supporting processing table 11 and the swing lifting plate 142 are vertically connected, the motor 123 inside the motor 123 is used to rotate the threaded rod, and the slider 124 is moved toward the inside of the furniture iron plate 13 under the limitation of the limit groove 122. At this time, the arc welding head 125 on the outer surface of the slider 124 is used to weld the joints of the two furniture iron plates 13, so that the two furniture iron plates 13 are positioned and fixed together.

[0030] Working principle: Place two furniture iron plates 13 on the top surfaces of the support processing table 11 and the swinging lifting plate 142 respectively, and perform position limiting processing on the two furniture iron plates 13 through the fitting positioning plate 114, the pushing plate 146, and the falling telescopic plate 148. At this time, the swinging lifting plate 142 is flipped by the second motor 14, so that the two furniture iron plates 13 are vertically overlapped with each other, as Figure 1 shown. At this time, cooperate with the first motor 123 inside the first motor 123 to move the slider 124 into the interior of the furniture iron plate 13, and then weld the joint of the two furniture iron plates 13 through the arc welding head 125; After the two furniture iron plates 13 are welded, an L-shaped state will be formed. At this time, cooperate with the fitting positioning plate 114 to relax the surface of the furniture iron plate 13, and use the second motor 14 to rotate the swinging lifting plate 142 in the reverse direction. Since the surface of the pushing plate 146 has been squeezing and fitting on the surface of the furniture iron plate 13, the firmly fixed furniture iron plate 13 will rotate together with the rotation of the swinging lifting plate 142. At this time, cooperate with the falling telescopic plate 148 to retract the output end, and then push the pushing plate 146 through the third motor 145, as Figure 2 shown, move the furniture iron plate 13 to the top surface of the moving roller 111, and then perform extrusion clamping processing on the position of the furniture iron plate 13 through the fitting positioning plate 114; After the furniture iron plate 13 is positioned, cooperate with the second motor 14 to rotate the limiting roller 141, so that the swinging lifting plate 142 at one end of the limiting roller 141 rotates around the support processing table 11 as the axis point. At this time, use the falling telescopic plate 148 to limit the height of the furniture iron plate 13, and make the swinging lifting plate 142 perpendicular to the top surface of the support processing table 11. After being perpendicular, the furniture iron plate 13 will be edge-to-edge with another furniture iron plate 13 on the top surface of the support processing table 11, so that the two furniture iron plates 13 can be effectively overlapped with each other. At this time, the two furniture iron plates 13 are in a vertically fitting state, which is convenient for subsequent employees to effectively weld the gaps between the two furniture iron plates 13, avoiding the need for employees to support and hold the two furniture iron plates 13 with one hand when welding metal plates, preventing the furniture iron plates 13 from shaking and being difficult to weld; Lay a new furniture iron plate 13 on the top surface of the swinging lifting plate 142 again, repeat the current operation, and lay a new furniture iron plate 13 on the surface of the previously welded furniture iron plate 13, as Figure 3 shown. After three furniture iron plates 13 are welded, as Figure 4 and Figure 5As shown, the current steps are repeatedly operated, so that after the four furniture iron plates 13 are welded, the sliding force of the bottom surface of the furniture iron plate 13 is increased by cooperating with the moving roller 111, so as to lift the furniture iron plate 13 from the top surface of the supporting processing table 11.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention.
